Our Carbon Steel DIN125 Flat Washers are precision-engineered sealing solutions designed to provide optimal load distribution and leak prevention in high-pressure environments. Manufactured from high-grade carbon steel and available in various surface treatments, these washers serve as critical components for pressure vessels, towers, tanks, and valve covers, ensuring structural integrity and operational safety.
Designed to meet rigorous national standards including GB95, GB96, and GB97 series, our fasteners are particularly effective for the chemical and petrochemical industries. Whether used in bolted flange joints or as non-metallic flat gaskets, these components prevent the leakage of internal media, offering a reliable seal between flanges in demanding industrial applications.
